\ RAIL-JOINT.

' Specification of Letters Patent. Application filed July 29, 1am.Serial no. 781,787.

' is a specification.

I11 the known rail joints (butt-joints with fish plates) the contactingsurfaces of the fish plates and the" rails become prematurely worn out,particularly opposite the gap of the joint, and the, play thus producedbetween the parts in question cannot beremoved by screwing the fishbolts farther home. This wear and tear is caused by the constantvibrations and shocks occurring during the operation of the line, theseinfluences causing in their turn. a rubbing movement of said contactingsurfaces; the obnoxious result of this movement will be obviated best bypreventing the movement itself, and a variety of contrivances havealready been proposed forv this purpose. For instance wedges and wedgeclamps have been arranged within the fish plates below the foot of therail,.or the latter has been clamped in a similar, but somewhat modifiedmanner, or clamping pieces have been inserted between the head and thefoot of the rail, in connection with fish plates the legs of which wereappropriately recessed below said head; and so on. At any rate,

an actual success has not been attained either by the before mentionedmeans, or by the application of a centrally arranged fish bolt. passedthrough the gap between the rails.

Now, the drawbacks stated have been fully overcome by my novelconnection which does not permit ofany mutual rubbing action between thefish-plates and the rails. This novel connection is illustrated in theaccompanying drawing in, which similar letters denote similar partsthroughout the several views and in which Figure 1 is a vertical crosssection through theparts constituting the joint. Fig. 2 is a side viewof the same, Fig. 3 is a similar view drawn on a reduced scale andshowing a slightly modified form of construction. Fig. 4 is a plan ofthe parts shown in Fig. 4, some parts being shown in horizontal section, and Fig. 5shows two verticalcross sections through the, parts isof Figs. 3 and 4.

Referring to Figs. 1 and'2, the fish plate webs are provided, oppositethe gap of the joint, with longitudinal recesses a, the dimensions ofwhich are such that the parts'o' and a above and below each recessmay bepressed in between the head and the foot of the rail and' thus putunderan elasticten- ,sion. This is effected by means of the wedgeshapedpieces k which are inserted into the Patented May '19, 1914.

recesses-a just opposite to the gap'of the y joint and are connectedwith each other by fish plate parts 0 and u, or the pressure with whichthey are forced against the-head and provided with recesses and wedgepieces, for Y the purp'ose of efiecting a correspondingly more intimatecontact between those fish plates and the respective parts oft-he rail.

Having now described my invention, what I desire to secure by' LettersPatent of the United States is:

1. In a rail joi'ntfthe combination, with the rail ends, fish platescontacting with the head and the foot of said rail ends,'and having arecess in each fish plate, a wedge situated in said recess, and a boltconnecting the'two wedges with each other.. p '2. In a rail joint, thecombination, with the rail ends, fish plates contacting with the headand the 'foot of the rail, and having a longitudinal recess in. eachfish plate, a wedge situated in the middle part of said recess, and abolt connecting the two wedges with each other.

'3. In a railjoint, the combination, with the rail ends, fish platescontacting with the head and the foot of said rail ends, and having arecess provided. in each 'fish plate and adapted to turn this latterinto a closed frame, a wedge situated insaidrecess and adapted to beforced farther into the same in thedirection to the rail webs. a boltconnecting the two wedges with each other, and a bolt-nut'adapted toforce the wedges toward one another.

4. Ina rail joint, the combination, with a boltis extending at said gapthrough ape propriate recesses provide'din the webs of thetwo rails. Theelastic tension of the the rail ends, fish plates contacting with thehead and the foot of the rail, and having a longitudinal recess providedin each fish plate and adapted to turn the middle part of the latterinto a closed frame, a wedge situated in said recess and adapted tobeforced farther into the same in the direction to the rail webs, a boltconnecting the two wedges with each other, and a bolt-nut adapted toforce the wedges toward one another.

5. In a rail joint, the combination, with the rail ends, fish platescontacting with the head and the foot of said rail ends, and having arecess in each fish plate, a wedge situated in said recess, co-axialholes in the two wedges, and a bolt or bolts located in said holes andconnecting said wedges with each other,

6. In a rail joint, the combination, with the rail ends, fish platescontacting with the head and the foot of said rail ends, and

' having a recess in each fish plate, a wedge situated in said recess,co-axial holes in the two wedges, recesses provided in the websof therail ends at the joint, and a bolt passing through these recesses andconnecting the two wedges with each other.

In a rail joint, the combination, with the rail ends, fish platescontacting with the head and the foot of the rail, and having a'longitudinal recess in each fish plate, a

" in the direction to the rail webs, and means for thus moving the twowedges so as to make them foroe-thehorizontal parts of said framesagainst the abutting parts of the rail 'head and foot, substantially asdescribed.

In testimony whereof I aflix my signature in presence of two witnesses.
